This section describes different storage options for MapR Monitoring. The MapR Control System (MCS) relies on MapR Monitoring
components to display MCS metrics, but it can function without the monitoring components. Using MapR Monitoring to store
logs is optional.

OpenTSDB: Run the OpenTSDB service on five or more nodes for clusters over 100
nodes.

Services to Separate on Large Clusters

The following are guidelines about which services to separate on large clusters:

ResourceManager on ZooKeeper nodes: Avoid running the ResourceManager service on
nodes that are running the ZooKeeper service. On large clusters, the ResourceManager
service can consume significant resources.

Monitoring Services on CLDB Nodes: Avoid running the OpenTSDB, Elasticsearch,
Kibana, or Grafana services on nodes that are running the CLDB service.
